Default 92 corvette steam pipe

I am installing a 92 corvette engine and I need some help knowing the path of the 92 steam pipe system. If anyone has a 92 and a minute or two, could you send me the routing of the steam pipe. I think it Tees and one branch goes into the pressurized reservoir and the other hose connects to the throttle body, but I can't tell. I can only find steam routing for 93 and later and those are different. Any pics would be appreciated.

This is for an actual '92 C4 or is this for maybe a project using a '92 LT1 engine?

On a '92 C4 yes it is a one year routing but the throttle body inlet is from the upper radiator hose and the throttle body outlet is actually the inlet hose for the heater core. Heater hose routing is the '92 only aspect. Air bleed pipe to tee, tee to coolant reservoir and tee to radiator is I believe same for multiple years.

The air bleed pipe does have a short hose to a formed tee and a short hose from tee to the coolant tank but a length of pipe forward. #29 in this image is that fabricated part. It I believe should go to the radiator if it's a C4 '92

Mr Dragon has a sweet C3 project that he is putting a ZF and lT1 in. Going to be rad.

Hey Mr SA, i love your projects and your style of video which is like a running commentary of the thoughts that go through many of us hobby dyi’ers. it was your vids —raw and just what they are—that made me record a recent trip i had with a CF friend with some great lt5 info. Thnx for the inspiration and i know the feeling of being burnt out on projects. Part of what keeps us going is sharing them here. Cheers.

okay. That’s really helpful. That means I’ll have to get a different radiator…. Hmmm. So in my pic, where does the hose I’m pointing to go?

I asked a fellow with a '92 that's very knowledgeable to stop by and check this thread.

The hose you've pointed to is currently routed as what? Is the LT1 installed or is this an engine still maybe on a pallet.
